Hhh
Nope! No flux issues or drum beating responces out of the whole amp as one , or just the circuit board!
When I die, I want to go like my Grandfather did, peacefully in his sleep.
Not screaming like the passengers in his car!
Cutting out a man's tongue does not mean he’s a liar, but it does show that you fear the truth he might speak about you!

Re: Taking bets!
Have you tried bypassing the standby switch with a clip lead? Is there a fuse in the B+ line?

Nope, the switch is in the circuit where the amp would have the issue all the time and it does not.

Re: Taking bets!
Oh, this sounds like new information then. In your original post, you say the noise occurs every 2 to 3 minutes. But now you're saying it doesn't happen all the time. Can you elaborate on what's different when you do not here the arcing noise?

Re: Taking bets!
Another known source of pops is the heater-cathode voltage breakdown in CF's. Is there a CF in that amp?

Ok headway!
I replaced the two PI output coupling caps with not change and then since my order for more 9 pin sockets has not shown yet I disconnected the plate feed wire to pin 1 and the issue stopped. I am calling it arcing socket for now until I suff in a new one.
